ROUND'IOP-WORK CONSTRUCTION.

Specification of Letters Patent.

Patented Mar. 16, 1915.

Application filed December 17, 1914. Serial No. 877,778.

To all whom it may concern Be it known that I, WILLIAM H. BOHNER, acitizen of the United States, residing at Knoxville, in the county ofKnox and State of Tennessee, have invented certain new and usefulImprovements in Roundtop -Work Constructions, of which the following isa specification.

This invention relates to round top work, or, in other words, to theconstruction of built up or veneered table tops and the like, and has asits object to disclose a construction such as to not possess thedisadvantages presented by the ordinary constructions now made use of.It is of course well understood that in work of this character, it isdesirable above all that the top have the appearance of being cut from asolid piece of the wood which it is desired to imitate, but thisappearance is not present in structures in which the edges of theveneered plies are exposed to view. In a well known and much usedconstruction, the upper end or edge of the rim of the top is flush withthe upper surface of the core of the top and the veneering which coversthe upper surface of the core overlies the upper edge of the rim so thatthe edges of the veneer plies are exposed to view. When a top of thisconstruction is stained or otherwise finished, the exposed edge portionsof the veneer plies will absorb more of the stain than the outer surfaceof the rim and as a result a dark streak appears at the upper edge ofthe ront of the work which renders the finished product unsightly besidepresenting certain other disadvantages as will be presently pointed out.In another well known construction, a strip of the veneer is applied tothe face of the rim of the top and extends completely to the plane ofthe upper surface of the top in its finished condition. So long as thisconstruction is viewed directly from the front, it has the appearance ofbeing cut from a solid piece of material but when viewed from the top orin perspective a dark streak is visible at the curvilinear edge of theupper surface of the top. If anything, the appearance of this work ismore unsightly than that of the first described construction and itpresents, in other ways, even greater disadvantages, as will also bepresently pointed out.

In consideration of the foregoing facts, it is the aim of the presentinvention to provide a construction of round top work such that theedges of the veneer plies will not be exposed to view and the entirework will have the appearance of having been cut from a solid piece ofmaterial.

Another disadvantage presented by work of a construction in which theedges of the veneer plies are exposed at the surface of the work is thatmoisture is liable to enter beneath the plies causing them to warp andbecome separated at their edge portions from the core, which of courseutterly destroys the appearance of the finished product.

It is therefore an aim of the present invention to disclose round topwork construction in which the edges of the veneer plies will not be soexposed as to permit of permeation of moisture between them and the coreof the work.

Still another disadvantage presented by work of this class in which theedges of the veneer plies are exposed, is that objects coming in contactwith the top are liable to chip or tear off portions of the said pliesat their edges, and this is particularly true in that construction abovebriefly described in which the upper edges of the veneer plies upon theface of the rim are exposed at the upper surface of the top.Furthermore, in such constructions, articles disposed upon the edge ofthe top or coming in contact with the edge are liable to dent the edgeportions of the surface veneer plies as these portions of the plies arenot supported in such a manner as to effectually resist blows or anyconsiderable pressure.

The present invention therefore further aims to provide round top workconstruction in which the edge portions of the veneer plies will beeffectually supported and braced and protected from being chipped ordented by contact with other objects.

The invention also aims to so construct the work that the core may beveneered before the rim is applied, which is impractical in the othertypes of such work above described.

In the accompanying drawings: Figure l is a fragmentary perspectivesectional view of the construction embodying the present invention. Fig.2 is a elevation thereof.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the accompanying drawingsby the same reference characters.

The work embodying the present invention includes a top proper which isindicated in general by the numeral 1 and a rim, indicated in general bythe numeral 2. The top 1 includes a core which is indicated by thenumeral 3 and which may be, as is usual, of an inferior quality of wood,and this core may be of any desired thickness as will be readilyunderstood. To the upper surface of the core 3 there is applied, byanyof the well known methods, an under ply 4 of veneering and a facingply 5. The plies 4 and 5 are so arranged that their grains will cross,and as is customary, the ply 4 is of softer wood than the ply 5. In alike manner backing plies 6 and 7 of veneering are applied to the underside of the said core 8. In carrying out the present invention, theplies 4 and 5 and the plies 6 and 7 are applied to the upper and underfaces of the core 8 respectively in the usual manner and this portion ofthe work is then sand papered and cut to the desired shape fragmentaryfront Zand size; Along its" curvilinear edge the top is provided with abevel or miter-cut 8 touching the outer edge of the upper surface of thefacing ply 5 andextending down- Wardly and inwardly from this edge, asshown in Fig. 1 to an intermediate point in the thickness of the core 3,below which point the said curvilinear edge of the top is provided withthe usuallocking bead 9, which, being of the ordinary construction,requires no further description. This portion of the Work is ofthe Wellknown fiveply construction, but it will be readily understood that ifdesired minor changes may be made. It is essential, however, that thebevel 8 extend to the extreme outeredge of the upper surface of thecasing ply 5 and it will be understood that, inasmuch as the beveliscontinuous and unbroken, it comprehends in its area the outer edges ofthe plies4 and 5 as-well as a portion of the outer edge of the core 3. V

The rim of the work is made up of any desired number of plies 10 ofveneering and these plies are preferably of equal thickness andindividually thicker than any of the plies 4, 5, 6 and 7. The plies l0are secured together in any ordinary and well known manner and afterbeing properly united the upper edge portion of the rim is cut on abevel, as indicated at 11, and the inner surface of the rim is providedwith the usual groove'lQ to receive the locking bead 9. V

'In assemblingthe work, the rim is disposed at the curvilinear side ofthe top in the positioF shown in Fig. '1 and secured'in place in anywell known manner. It will be observed that the bevel 11 matches thebevel 8 and that the bevels are of the same extent so that the outerupper edge of the bevel 11 registers with the corresponding edge of thebevel 8. It will also be apparent that the beveled edges of the plies 4and 5 are completely covered and concealed by the upper portion of thebeveled surface 11. Furthermore, it will be observed that the outer oneof the plies of the rim is of a thickness greater than the combinedthickness of the plies 4 and 5 and that as a consequence thebeveled'upper edge of this ply not only extends beneath the beveledouter edges of the plies 4 and '5 but also, as indicated by the numeral13, beneath the extreme outer cdgeportion of the core-3 so that a firmsupport is afforded the beveled edges of the plies 4 and 5 and also theportion of the core which extends beneath'the outer edge portion of theply 4.

From the foregoing description of the invention it will be seen that theedges of the veneer plies are completely covered and protected and arenot exposed to view. It 7 will also be apparent that the edges of theplies 4 and 5 are effectually supported by the solid and relativelythick outer ply 10 of the rim so that any object strikin against theedge ofthe top will not be liable to dent the edge of the ply 5 nor tochip or tear this ply and the ply 4. It will be obvious that the workconstructed in accordance with the present invention will present theappearance of having been cut from a solid piece of material and that,in other respects, the work will not disclose the fact that it is builtup and veneered except upon 7 very close examination of the portionsthereof, which, in any event, are not ordinarily exposed to view.

Having thus described the invention, what is claimed as new is: I

1. In wood work construction of the class described, a top including acore and a veneer ply, the edge of the core and ply being cut on abevel, and a rim having an edge out on a bevel and secured against thebevel of the core and veneer ply of the top, the rim at the upper edgeofits'bevel being flush V with the upper surface ofthe veneer ply.

2. In wood work construction of the class described, a top including acore and a vene'er'ply, the edge of the coreand ply being cut on abevel, and a rim having'an edge out on a bevel anddisposed with itsbevel matching the bevel of the core and veneer ply and secured thereto3-, In wood work construction of the. class described, a top including acore and a veneerply, the edge offthe core and ply being cut on a bevel,and a rim'having an edge out on a bevel and disposed with its bevelmatching the bevelofthe core and veneer ply and secured thereto, the rimcomprising In testimony whereof I affix my signature assemlgled pligsand tlliglouter one of the said in presence of two witnesses.
